Well, her jaw and everything too.  Here's the problem, I'm using Vickie 4.2, and when I change her pose via the head or neck... the teeth seem to pop out of her head, forcing me to close without saving to try again.  Any ideas on what I should do to fix? 

Thank you for any helpful ideas you might have, aside from my packing up my computer and not touching it. =P

do you have her eyes set to point at something ? I seem to remember this can cause the problem you are seeing (but don't ask me why)

This happened to me on a few occasions, and I asked the same question. I was advised just to save the scene, close Poser and then re-open, and the problem would be fixed. And it was.

The strange thing was that moving the head left the teeth behind, but moving the neck (and head of course) didn't.

Thank you both.  I think it's that I have the eyes pointing at a camera.  I'll re-do things without that and see how it works.  Thanks again!

I have this same problem.  I found that if you select the upper jaw and then turn the side to side dial, the jaw will pop back in.  It's alot easier than closing everything and reopening.

When you're in a given frame, you can usually just switch to another camera (e.g., the Face Camera) and rotate it.  The parts pop back in and you can switch back to your prior camera.  This is easier than moving body parts.  However, this solution (and all others I've ever heard of) fail to address "lock jaw" for animations. 

Thank you, as I only do still renders at this time, that was immensely helpful and a good deal easier than the bodyparts suggestion.

Thank you ALL for your help in this, it is really appreciated.

You're welcome.  If one uses the keyboard shortcuts to switch cameras, it can be very quick.  Anyway, glad this now works for you.  cheers...
